DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for simulating the operation of a system and displaying a simulation result, and more particularly to an input and a display.

[0002]

2. Description of the Related Art As for verification of a system, for example, a real-time system, there are the following techniques regarding verification and display thereof at the time of function design.

Conventionally, as an example of an operation display device (information processing device) for confirming a result of simulating a program for operating a real-time system, a real-time system is disclosed in Japanese Patent Application No. 2-316125. In some program objects, the designer describes (programs) the contents of a state transition table or state transition diagram in an object-oriented language. Then, the program is simulated for program verification, and the obtained operation result of the system is displayed on an editable real-time system operation display device,
It was verifying whether there was a program error. However, describing the contents of a state transition table or state transition diagram in a special object-oriented language for program verification, together with programming for the original program design, is a double design task. Burdensome.

As another conventional technique, there is one in which a state transition specification (state transition table or state transition diagram) is directly input. An example of such a verification and display device is described in JP-A-3-14037 and JP-A-3-171364.
A result of simulating a program for operating a real-time system is output in a form (list form) equivalent to a state transition diagram. However, since the output state transition diagram is a verification display device using a list, there is a problem that it is very difficult to confirm the simulation results as an execution / display device for an actual real-time system model. There is a problem to say. .
